Solution

1. Preparation

Gather tools: a Phillips screwdriver, a measuring tape, and a flathead screwdriver for adjustments.
Ensure the vehicle is on a level surface and the headlights are clean.

2. Access Headlight Adjustment Screws

Open the hood of the Porsche Cayenne.
Locate the headlight assembly; there are typically adjustment screws on the back or top of the assembly.

3. Adjust Vertical Alignment

Identify the vertical adjustment screw (usually labeled “up/down”).
Use the Phillips screwdriver to turn the screw:
- Clockwise to raise the headlight beam.
- Counterclockwise to lower the headlight beam.
Adjust until the light beam aligns with the mark made on the wall.

4. Adjust Horizontal Alignment

Identify the horizontal adjustment screw (usually labeled “left/right”).
Use the flathead screwdriver to turn the screw:
- Clockwise to move the beam to the right.
- Counterclockwise to move the beam to the left.
Adjust until the beam is centered on the mark.

5. Final Check

Turn off the headlights and close the hood.
Recheck the alignment by turning the headlights back on and ensuring the adjustment is satisfactory.
